Is there a filter that will perform:

Brightness
- I'm sure I can use the offset on MV Color Twist

Saturation

Hue
- Again Color Twist

Contrast

I'm kind-of a newbie on color manipulation.

Thanks for your patience,
Mark

Hi Mark,

You can use the color twist matrix to perform the following operations:

Lightening an image
Color saturation
Color balance
R, G, and B color adjustments
Contrast adjustment.

You can find a good tutorial here: http://www.sigmapi-design.com/htmtutor/ctwist.htm

For brightness and contrast adjustment you can also use a look up table as implemented in our MV LookUpTable filter.


Best Regards,
